To all whom it may concern:

Be it known that we, ABRAHAM Praslin and HARRY Coi-1N, both citizens of the United States, and residents of the city of New York, borough of the Bronx, in the county and State of New York, have in vented a new and lmp roved ilVire-Frame Machine, of which the following is a full, clear, and exact de scription.

This invention relates to wire frame machines, and more particularly to machines for forming wire hat frames and the like, and each having a plurality ofarms carrying wire holders which are adjustable longitudinally of the arms and transversely thereof, and which can be clamped securely in a plurality of positions upon the arms, the latter being pivoted and being simultaneously operable to release a wire frame formed upon the holders.

An object of the invention is to provide a simple, strong and durable wire frame machine which is capable of a plurality of adj ustments to permit frames of widely differing forms to be fashioned thereon, and which can be operated to release a frame after the latter is formed, without distorting or altering the form of the frame.

A still further object of the invention is to provide a wire frame machine which is comparatively inexpensive to manufacture, in which wire holders of different forms can be employed, and in which the wire holders are capable of a great range of adjustment and can be held. securely in any adjustment, so that there is no danger of their slipping while a frame is being formed.

The invention consists in the construction and combination of parts to be more fully described. hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in whichM Figure 1 is a transverse section of the ma chine on the line 1-1 of Fig. 2 Fig. 2 is a transverse section on the line 2 2 of Fig. 1 Fig. 3 is a side elevation showing one of the wire holders; Fig. 4 is an enlarged perspective view of one of the carriers or clamping members for the wire holders; Fig. 5 is a side elevation showing a wire holder of modified form; and Fig. 6 is an enlarged transverse section showing means of modified form for securing the wire holders upon the arms.

Before proceeding to a more detailed exe.

planation of our invention, it should be clearly understood that while the same is particularly useful for forming wire hat frames, it can also be advantageously employed for forming other frames of wire er the like. In this art, it is customary to employ a plurality of wire holders upon which the wire from which the frame is fashioned, is wound and held while being formed into the frame. The wire holders are adjustable so that frames of different forms can be fashioned thereupon. Our invention. provides means for mounting the wire holders so that they are capable of a great many adjustments, and at the same time, when adjusted can be firmly clamped in position and held against casual displacement. Furthermore, in our machine the wire holders are simultaneously movable to release the frame after the latter has been formed, without the danger of bending or distorting any part of it.

Referring more j iarticularly to the draw ings, we provide a base l() which may be mounted upon a table or other support by means of screws 11 or in any other convenient manner. The base 10 has a substan tially central upright post 12, upon 4which is rotatably mounted a standard 13 having the lower portion hollow to receive the post 12 and to form a bearing therefor. At the upper end, the standard 13 is formed into a hollow outwardly extended head 14, having a rim 15 consisting of straight sections 16 angularly disposed with respect to one another. Each of the sections 1G has a recess 17.

Vithin the head 1d is a hub rod 18 slidably extending into a bore 19 of the standard and having a crown 20 having outward peripheral extensions 21. Each of the latter has a pivot pin 22. A top 23 conforming in shape to that of the head 111 has a rim 2d provided with recesses 25 each of which is adapted to register with a recess 17, and forming with the latter, slots through which the arms 26 extend. The latter are pivotcd upon suitable pins 27 journaled in bearings formed between the rim 15 and the rim 24. The inner ends of the arms 26 are piv otally mounted by means of suitable openings, upon the pins 22 ol' the crown 20. The to prevent the holders lfrom sliding through latter has pivoted thei'eto a link 28 which is controlled by a lever 29 pivoted in a slot 30 of the head and having a handle 31 by means el which it can be manually operated. The lever 29 serves to raise or lower the hub rod 18 and its crown, to swing the arms upwardly and inwardly for a purpose which will appear more clearly hereina'lter. The top 23 is mounted upon the head by means ol' screws 32 or in any other convenient manner.

Upon each oll the arms 26 is slid ably mounted one or more blocks 33 having a suitable opening for the purpose, and prow vided with threaded stems 34. Each olVl the blocks has a sleeve 35 mounted thereon and has a set screw adapted to engage a longitiidinal groove 37 ol the arm to secure the bleek 33 iirmly upon the arni at any desired point ol' the latter. Upon each stem 34 is located a plurality olI wire holder carriers consisting prel'crably ol' disks or plates having substantially central openings 39 to receive the stem, and provided with a segmental undercut recess or groove 4() in one l'ace.

The wire holders 41 are preferably in the Vl'oriii el'l elongated rods having at one end hooks to hold the wire, er notches 42 ior a like purpose. lt will be understood that the l'iolders 41 may be bent or curved into any suitable form and may be l'asliioned to suit individual preference or special conditions. The holders are termed to lit slidably into the grooves 40 and to extend slightly beyond the adjacent laces ol the carriers 38. Each olI the stems 34 has a nut 43 which serves to jam the parts together and to lock the carriers as well as the holders in any desired position. lt will be seen that by adjusting the nuts 43, the carriers 38 themselves serve to secure the holders in position, as each oi'l the latter extends slightly beyond its carrier, and at the same time the carrier adjacent to the sleeve 35 ams the latter against the arm 26 thus serving to hold the bleek upon the arm.

ln Fig. 5 is shown a wire holder of modified Aform which has an extended portion 44 provided with openings 45 each et which is adapted to receive directly, a stein 34 so that the carriers 38 can be dispensed. with. In the modiiied detail shown in Fig. 6 a block 46 is shown mounted upon an arm 26 and having on its stem 34 a loose U-shaped bracket 47, the arms 48 oi which have the extremities curved to seat upon the arm 26, and which is jammed against the latter to lock the parts in position when the nut 43 upon the stem is tightened. It will be understood that the nut 43 may be el any suitable lorm, for example, an ordinary nut, or a butterfly or thumb nut.

The holders 41 have extended portions 49,

the grooves 40 and falling vfrom the arms when the nuts are loosened to adjust them.

The arms are adjusted in accordance with the design o1' the 'frame to be l'ornied, and the wire A lrom which the Vframe is fashioned is then Wound upon the holders engaging the grooves 42, as shown most clearly in F ig. 2. lllhen the Yframe is completed and it is desired to remove it from the machine, the lever 29 is raised so that the iod 18 is moved downward, carrying with it the crown, and swinging the arms 2G uj'iwardly and inwardly as indicated. in Fig. 2. The simultaneous movement ol' the arms releases the holders from the wire and permits the l'rame to be removed from the machine, without distortion or other injury.
